The story begins with Thomas, waking up in the elevator, or "the Box" as "the Gladers" call it.
Thomas finds out he's stuck in some sort of floating prison. The only way out is through a huge maze, which changes every night.
The emotions and thoughts of the characters are described very well.
As reader, I get fully immersed into the story and the plot is well structured too.
The mysterious background story is also very interesting and it's clear the author doesn't want to spoil everything, which only amplifies my curiosity as the reader.
I recommend this book to anyone who likes dystopia stories, such as the hunger games and divergent.
